A contraceptive implant is an implantable medical device used for the purpose of birth control.The implant may depend on the timed release of hormones to hinder ovulation or sperm development, the ability of copper to act as a natural spermicide within the uterus, or it may work using a non-hormonal, physical blocking mechanism.
Technique depicted in 3D video This image shows how Nobel Biocare's All-on-4 solution works. The term All-on-4, also known as All-on-Four [1] and All-in-Four, [2] refers to 'all' teeth being supported 'on four' dental implants, a prosthodontics procedure [3] [4] for total rehabilitation of the edentulous (toothless) patient, or for patients with badly broken down teeth, decayed teeth, or ...
Upon follow-up, occlusion was observed to have occurred in 96.5% of patients at 3 months with the remainder occluded by 6 months. [8] A 2015 study published in the BMJ concluded that Essure was as efficacious as laparoscopic sterilization at preventing pregnancy, but with a "10-fold higher risk of undergoing re-operation" when compared to ...
Patients who had tubal occlusion surgeries have been found to be four to five times more likely to undergo hysterectomy later in life than those whose partners underwent vasectomy. [5] There is no known biologic mechanism to support a causal relationship between tubal ligation and subsequent hysterectomy, but there is an association across all ...
The AO's contributions to the field, including but not limited to the current usage of internal fixation implants, surgical techniques, and clinical resources, have a significant impact in the way orthopaedic trauma surgery, spine surgery, craniomaxillofacial surgery, and joint preservation and replacement surgery are performed.
Occlusion of the left atrial appendage can be achieved from outside the heart (the Lariat device) or from inside the heart (endovascular) with a blood-exposed implant (the Watchman and Amulet devices). The first method is a form of ligation that eliminates perfusion of the LAA.
An inferior vena cava filter is a medical device made of metal that is implanted by vascular surgeons or interventional radiologists into the inferior vena cava to prevent a life-threatening pulmonary embolism (PE) or venous thromboembolism (VTE).
